Humans are an aggressive violent species - especially, but not only, young males. We always have been and unless/until we evolve, always will be. The sooner we stop acting in as much denial of that as the Victorians were in about sex, the better. My solution would be to give young people who opt-in - because not all young men are aggressive, not all women of any age aren't - some reasonably safe way to express that natural aggression without taking it out on the Middle East and/or ruining their prospects for life with criminal records. Rant over!
